Final answer:
Brighter, lighter lip colors are best used on thinner lips to make them appear fuller. Lip stains offer a long-lasting, matte look, whereas lip balms provide essential moisture and protection for the lips.
Step-by-step explanation:
You should use brighter, lighter lip colors on thinner lips. These shades can make lips appear fuller and more prominent. On the other hand, lip stains provide a matte look and are more long-lasting due to their water or gel base and the inclusion of alcohol in some formulas. This type of product may be applied with a variety of tools like an applicator brush, rollerball, or a finger.
For lip care, lip balms are an essential tool as they moisturize, sometimes tint, and protect the lips, with some even containing sunscreen to prevent damage from UV rays. Moreover, using a lip primer or balm before applying lipstick or lip stain can help to prevent chapped lips.
